Wow, for a moment I thought I could use this hack to access the Log module:

   After_options ->
     (* Automatic -classic-display when not in a terminal *)
     if Sys.getenv "TERM" = "dumb" then
       Ocamlbuild_pack.Log.classic_display := false

But it has no effect. Maybe moving classic_display to the Options module 
would be great, if it has not been done already (I'm still in 3.10.1) ^^
